Read that. Counterclockwise = lower shift points right? Havent tried that yet.
I also think Trans may have a shift kit- when I pulled the small piston behind the modulator it was missing the spring. I understand that a shift kit will eliminate that spring.
Dont know much about Th400s, stick to 4 speeds usually.
